1 A Mainframe Guy and Cloud Computing Per Fremstad, IBM pensjonist 2

2 Computing models: A bit of history 1950 s / 60 s / 70 s - Centralized Sharing and reliability Dumb, text-based terminals ----> PC s 1980 s - Distributed client server Low costs and simplicity PC s ----> mobile devices and sensors Mid 1990 s - Internet / Web On demand computing 3 The New Cloud Computing Model Internet / Web Linux / Open Source Grid Autonomic..SOA..On Demand Web 2.0 Social Networking Explosive rise of intelligent mobile devices - Blackberrys, iphones, notebooks, sensors A confluence of forces building over the past decade.the evolution of the internet 4

3 What is cloud computing? A user experience and a business model Cloud computing is an emerging style of IT delivery in which applications, data, and IT resources are rapidly provisioned and provided as standardized offerings to users over the web in a flexible pricing model. An infrastructure management and services delivery methodology Cloud computing is a way of managing large numbers of highly virtualized resources such that, from a management perspective, they resemble a single large resource. This can then be used to deliver services with elastic scaling. Monitor & Manage Services & Resources Cloud Datacenter Infrastructure Access Services Cloud consumers Cloud Administrator Service Catalog, Component Library Staff and cloud facilitators Publish & Update Components, Service Templates 5 Some Characteristics of Cloud Computing Internet of Services User experience Decouple delivery from technology Process-oriented, industrialized approach Virtualized Assets Security Green footprint Multi-tenant Flexible acquisition model 6

4 Cloud Computing Delivery Models Flexible Delivery Models Public Service provider owned and managed. Access by Subscription. Delivers select set of standardized business process, application and/or infrastructure services on a flexible price per use basis.. Standardization, capital preservation, flexibility and time to deploy Cloud Services Cloud Computing Model Hybrid Access to client, partner network, and third party resources Private Privately owned and managed. Access limited to client and its partner network. Drives efficiency, standardization and best practices while retaining greater customization and control. Customization, efficiency, availability, resiliency, security and privacy ORGANIZATION CULTURE GOVERNANCE...service sourcing and service value 7 Why the crazy interest in cloud computing today? IT needs to deliver service, to meet the needs of the business you are supporting IT has not been doing a good job of this. Users are not satisfied A private cloud is a model for IT to do a better job of delivering services to end users IT needs to operate as a value center. When IT is a cost center, the only thing they ask you to do is cut costs! 8

5 End to End Cloud Computing Issues Consider Disaster Recovery Replication between machines in a room is not DR Compliance How will Cloud providers put you at risk Security Secure the data. Multi Tenancy issues Selecting appropriate workloads Cloud technical models do not solve all problems. Translating what you know into corporate value Legal definitions of technical issues 9 The mainframe for cloud computing "It's a mainframe model where things run together but in isolation. The issue is whether the machines will bear up under the load of diverse work or will they grind down and you'll need to provision another machine. You need reliability, security, auditing, privacy, data integrity, automation and full isolation." - Steve Mills, IBM Sr VP Strong TCO Energy efficient Near-linear scalability Capacity management & upgrades on demand Delivers a specialized IT environment Virtualizes from the silicon to the app Enables transparent multi-tenancy of applications Improves performance Comprehensive industry-leading security Enables seamless reliability 10

6 System z provides a hybrid -aas hosting environment The core infrastructure of System z is multi-tenant by nature and highly efficient, resources (HW and SW) are shared and virtualized to ensure max utilization enabling you to deploy workload for fit. SaaS Data warehouse zsaas Landscape SaaS virtual server warehouse z/os Sysplex Shared Infrastructure DB2 (Data Sharing) HyperSockets zvm/linux Multi-Tenancy virtualization Virtual Servers Biz Svc 1 Biz Svc 2 Biz Svc 3 11 Pain Point System z Power x86 Avoiding downtime Best Unmatched system reliability and redundancy of server hardware assets. Better Good Managing growth Best Dynamically add real hardware; share system resources with multiple hypervisors in a single machine. Better Good Underutilized Resources Best (up to 100%) Extensive hardware sharing as you scale; extremely granular sharing of system resources. Better (~ 80%) Moderate hardware sharing as you scale Good (~ 50%) Very little hardware sharing as you scale Need for flawless system monitoring Best Superior statistics and operational insight. Better Good Workload management Extensive Also able to span architectures with zenterprise (z/p/x). Moderate Minimal Time to market Best Server cloning can be achieved in seconds; granular and efficient sharing of resources facilitates rapid provisioning. Better Good

7 Enterprise focus on private cloud Infrastructure as a Service Development and Test Instances Best place to start Quicker instance availability Change the time to value of development Easier to demonstrate value Non production Sophisticated user profile Challenges Cloud crosses multiple Silos Building consensus takes time 13 Immaturity of support processes What does all this mean to a mainframe person? Distributed models are learning what the mainframe already does Clients are beginning to use z/vm and zlinux to provide IaaS and PaaS Linux images can be built up quickly Address spaces on z/os can be spun up We can be the private cloud for the enterprise 14

8 Closing Thought..Doesn t Every Business Want What Cloud is Trying to Deliver? Wide variety of consumer and business services delivered to a large number of clients around the world Operate highly scalable, well-engineered, efficient data centers delivering service with high quality and reasonable cost Green Secure Service Level Agreements in place 15 IBM System z Cloud Blueprint Integrate Take out cost Consolidate and Virtualize Differentiation Rapid deployment of Linux virtual servers for less than one dollar a day Industry leading "gold standard security for tenant isolation Elastic scaling achieved by dynamically adjustable capacity at sustained performance Multisystem virtualization simplifies management by clustering shared resources z/vm Linux on IBM System z 16 Automate Simplify Automate and Manage Better Standardization Automated provisioning and de-provisioning Pool standardized virtualized building blocks Plug-and-play capacity across hardware generations Capture and catalog virtual images in the data center Automated methods for faster delivery of services with higher levels of control Tivoli Provisioning Manager Available now SmartCloud Provisioning Available now SmartCloud Entry (Coming) Orchestrate Orchestrate Service Lifecycle Management Service Management Integrated virtualization management with IT service delivery processes Self-service provisioning Automated service lifecycle management including dynamic instantiation of cloud services Pay for use Optimize IT resources to reinvent business processes Tivoli Service Automation Manager Available now SmartCloud Orchestrator (Coming)
